I assume you've missed that you can buy dogs, sheep, cows, pigs, and reindeer in villages? Humans have used animal husbandry for a very long time, and that applies to backwaters such as Finland at the time as well.
Animal husbandry is listed on the dev page as one of the (many) future goals, but I guess you've missed that page?
It can be found at

Thus, it's not a matter of not intended, but rather a matter of not yet implemented. Young animals of various wild species is a small step in the direction towards husbandry. UrW develops very slowly, both because of the limited size of the team, and because there's an emphasis of keeping the game playable and as bug free as possible over rapid development.
There's a mod featuring chicken, and several that include sheep shearing (although they might have the same roots). I don't believe the mod ability allows for animal husbandry, though.
